Just thought you all would appreciate this info brought to you from Fallout. (also doubles to warn those looking to survive a single bullet from a sniper while in super) TL;DR To survive a single headshot while in super, you need an armor stat of 7 or higher for mid-high (31) impact rifles. Any lower will shut you down. There is [b]ABSOLUTELY NO WAY[/b] to survive a headshot from Black Spindle, Zen Meteor or Efrideet's Spear.
